Background/Description
The Brief Inventory of Thriving (BIT) is a 10-item self-report measure of psychological well-being. It was developed by Ruochen Su, Lokman Tay, and Ed Diener in 2014. The BIT measures six dimensions of psychological well-being:
- Relationships: Feeling connected to and supported by others.
- Engagement: Feeling involved and interested in life.
- Mastery: Feeling competent and capable of achieving goals.
- Meaning: Finding purpose and significance in life.
- Optimism: Having a positive outlook on the future.
- Subjective well-being: Feeling happy and satisfied with life.
The BIT was developed in response to the need for a brief and reliable measure of psychological well-being. The original version of the BIT, the Comprehensive Inventory of Thriving (CIT), had 54 items, which made it difficult to use in some settings. The BIT was created by reducing the number of items in the CIT while still maintaining the psychometric properties of the original scale.
The BIT has been shown to have good psychometric properties, including reliability and validity. It has been used in a variety of settings, including clinical, research, and educational settings.
The BIT is a free and easy-to-use tool that can help you assess your level of psychological well-being. If you are concerned about your well-being, you should talk to a mental health professional.
Here is a brief introduction to the six dimensions of psychological well-being that are measured by the BIT:
- Relationships: This dimension refers to the quality of your relationships with others. It includes feeling loved, supported, and connected to others.
- Engagement: This dimension refers to your level of involvement and interest in life. It includes feeling passionate about your activities and feeling like you are making a difference.
- Mastery: This dimension refers to your sense of competence and capability. It includes feeling like you can achieve your goals and feeling like you are in control of your life.
- Meaning: This dimension refers to your sense of purpose and significance in life. It includes feeling like your life has meaning and that you are making a difference in the world.
- Optimism: This dimension refers to your positive outlook on the future. It includes having hope and believing that good things will happen.
- Subjective well-being: This dimension refers to your overall happiness and satisfaction with life. It includes feeling happy, content, and fulfilled.
Administration, Scoring and Interpretation
o administer the BIT, you will need to:
- Provide the participant with a copy of the BIT.
- Instruct the participant to read each item carefully and rate their level of agreement with each item on a scale of 1 (strongly disagree) to 5 (strongly agree).
- The participant should answer all 10 items.
- Once the participant has finished answering the items, you can collect the BIT.
Reliability and Validity
The Brief Inventory of Thriving (BIT) has good reliability and validity.
Reliability refers to the consistency of the BIT scores. The BIT has been shown to have good internal consistency, with Cronbach’s alpha coefficients ranging from 0.83 to 0.90. This means that the items on the BIT are all measuring the same construct, which is psychological well-being.
The BIT has also been shown to have good test-retest reliability, with correlations between test and retest scores ranging from 0.75 to 0.85. This means that the BIT scores are relatively stable over time.
Validity refers to the extent to which the BIT measures what it is supposed to measure. The BIT has been shown to have good convergent validity, which means that it correlates with other measures of psychological well-being. For example, the BIT has been shown to correlate with the Satisfaction with Life Scale (SWLS), the Flourishing Scale, and the Positive and Negative Affect Schedule (PANAS).
The BIT has also been shown to have good discriminant validity, which means that it does not correlate with measures of ill-being. For example, the BIT has been shown to have low correlations with the Depression Anxiety Stress Scale (DASS) and the General Health Questionnaire (GHQ).
